摘要： A pixel array includes a plurality of sub-pixels, which include first to third sub-pixels. The first and third sub-pixels are alternately arranged along a row direction and form first pixel rows. The first and third sub-pixels, which are in a same column, in the first pixel rows are alternately arranged, and the second sub-pixels are arranged side by side along the row direction and form second pixel rows. Lines sequentially connecting centers of two of the first sub-pixels and two of the third sub-pixels, which are arranged in an array, together form a first virtual quadrilateral, and one of the second sub-pixels is in each first virtual quadrilateral. A straight line in the row direction or in a column direction, which passes through a center of each sub-pixel of at least one of the plurality of sub-pixels, divides the sub-pixel into two parts having areas different from each other.
